A no-brainer to me. It was bone-headed to let it get this far. What does Amazon most want to be?
* the company that sells everything to everyone at good prices?
* one of several companies with a video service that has a few nice exclusives
(not the most or best exclusives, either)?
I think it kind of snuck up on them that this was an either/or question and it took some time for them to make the obvious/right decision.
As an Amazon Fire Stick user I am somehow glad that they did that. YouTube is part of my daily TV watching and it would be be if I would have to change the device just to watch YouTube videos. Amazon s should open more widely their app store for third developers.
